If the angle b23 is inscribed in a unit circle then the coor

If the angle b=2?/3 is inscribed in a unit circle, then the coordinates of the point (x,y) are given by

Part 1:

Part 2:

1 point) (1,0 If the angle b- i inscribed in a unit circle, then the coordinates of the point (z, y) are given by is inscribed in a unit circle, then the coordinates of the point (x, y) are given by and y =

Solution

Angle = 2pi/3

Unit circle : x= 1*cos(2pi/3) ; y = 1*sin(2pi/3)

x = -1/2 ; y =sqrt3/2
